A few months ago I bought the Edge 205 and was really impressed with the improved accuracy over my Geko 301. Then, for Christmas I got the GPS60 csx. I've been riding with them both for a few weeks now, and I'm coming to the conclusion that the Edge is actually more accurate. I came to this conclusion just by plotting all of my tracks which cover the same trails multiple times. They are both pretty good, but the GPS60 seems to wander off route once in a while. I was a bit bummed by this because I expected it to be better than the Edge because it has this 'quad helix antenna', which is supposed to help. I was wondering if anyone else has made a head-to-head comparison like this? I did check for firmware upgrades for the GPS60, but everything seems to be up to date.
